I need to get professional help but i feel that my dad is the one who should be getting it and not me. Help!!?

well see the thing is I am suffering from severe depression ( cant focus on anything, losing appetite, loss of energy, and feeling of hopelessness) but i only suffer this because of the people who i live with mainly my dad. Like my dad is the horrible parent who made me feel like crap all the time. I feel like he should be the one going and getting some help because he wouldn't know the first thing about parenting. But yea how do i overcome that kind of thought? like and should i just go in to get some professional help?
